This posts make me to ask this question:
What I think is they keep fewer coins right now to avoid further losses; they can immediately buy BTC or any unstable coin if their customers decide to withdraw big winning amounts.
That's why I think the reason why there's no instant withdrawal if you withdraw a large amount except to a stablecoin.
On gambling sites, if you withdraw stable coins and unstable coins but the money withdrawn is huge, will stable coin be processed faster than bitcoin?
I am thinking they will be processed almost the same time until I read that post.
I don't think the casino will have any issues with user withdrawals, as long as the casino has ample liquidity to handle any large withdrawals its users might make. So, the casino can exchange any type of crypto asset they need. Furthermore, I believe a well-known casino with a large customer base should have substantial financial resources, as should its revenue. Therefore, I don't think a well-known casino will have any issues with user withdrawals, as the OP said. Besides that, I think network congestion problem is also one of the causes. Additionally, I suspect the casino might be conducting further inspections on large withdrawal, so they requiring more time to process it. Cmiiw.
